CONVERTIBLE SCREW-DRIVER AND BORER.

SPECIFICATION forming part of LettersPatent No. 274,0;12, dated March13, 1883.

Application filed September 4, 1882. (No model.)

To all whom "it may concern:

Be it known that I, HENRY V. SMITH, of Plantsville, in the county ofHartford and State of Connecticut, have invented new Improvements inConvertible Screw-Drivers and Borers; and Ido" hereby declare thefollowing, when tak-enin connection with accompanying drawingsandtheletters of reference maiked thereon, to be a full, clear, andexact description of the same, and which said drawings c0nstitute partof this specification, and represent, in-

Figure l, a side view, presenting the screwdriver; Fig. 2, a verticalcentral section; Fig.

3, same as Fig. 1, presenting the borer.

This invention relates to an improvement in an instrument for drivingscrews, the object being to combine in one instrument a device forboring the hole and a screw-driver, either of which may be usedasrequired; and it consists in a handle carrying a blade pivoted in thehandle, one end shaped to form a borer to make the hole for theinsertion ot' the screw, the other end a screw-driver, and arranged sothat either end may bepresented for work, the other inclosed within-thehandle, the handle constructed in two parts from cast metal, so as toform a central handle, within which the inactive end of the blade willbe inclosed, and

0 the two parts of the handle secured together by a transverse rivet,and the blade held in its active position by a collar sliding on thebody of the handle, as more fully hereinafter described.

The handle is made from two parts, A B, divided in a vertical orlongitudinal line, the two parts fitting together, and so that a rivet,U, inserted transversely through the head end will secure the two partstogether. The lower part of the handle has a central slot, D, formedhalf in each part, and opening to the right and left. In this slot/theblade is hung upon a pivot, a. The blade is shaped at one end to form ascrewdriver, 1, and the other end to 5 form a borer, F, the bladearranged so as to swing through the slot and presenteitber endsay asfrom the position in Fig. 1 to that in Fig. 3, or vice versa. The pivotthrough the blade and lower end of the handle serves to secure that endof the handle together; but as 0 the pivot is necessary to the blade,the pivot U is the only additional part required. The body of the handlefrom the lower end upward is made cylindrical, and on this cylindricalpart is a sliding collar, G, and which, when the blade is in the desiredposition, is moved down to near the lower end, where the bladecorresponds in width to the diameter of the handle, and in thatposition, as seen in the several figures, it holds the blade andprevents its turning uponthe pivot; but when it is desired to change theends of the blade,the collar G is moved upon the body away from thelower end, as seen in broken lines, Fig. 1,- which leaves the slot freefor the turning of the blade.

By this construction I am enabled to cast the handle with the slot, andalso to cast the handle hollow without a core, and thus pro-' duce avery cheap handle, and with this convertible borer and screw driver Iproduce an article convenient for joiners and others.

As an article of manufacture, the hereindescribed screw-driver andborer, consisting of the handle made in two parts, A. B, slottedtransversely, divided longitudinally through the slot, a blade hung upona pivot in thelower end of the handle, arranged to turn through the slotand present either end outward, the other end being in the slot withinthe handle, the body of the handle cylindrical, combined with a collar,G, arranged to slide upon the body of the handle, and the two parts ofthe handle secured together, all substantially as described.
